commit: https://git.buildroot.net/buildroot/commit/?id=27024049426483091b1d5edc73cd225307e79540
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master
Currently, the cmdline.txt file is installed in $(BINARIES_DIR) by the
rpi-firmware package. Overriding files in there can not be done with an
overlay (which only applies to $(TARGET_DIR)), and thus requires using
either a post-build or post-image script, which is not always very
practical when a custom file must be used.
Like was done in 689b9ac439ab (package/rpi-firmware: rework boot/config
file handling) for config.txt, add an option to allow users to specify
the path to a custom cmdline.txt.
